“snow” on the screen.
m Make sure the display cable is connected firmly to the correct port on the
back of the computer.
If you have a video card installed in your computer, the display cable should
be plugged into the port for the video card.
If you do not have a video card installed in your computer, the display cable
should be plugged into the display port on the back of your computer.
There are wavy lines on the screen, creating an optical effect or moiré pattern.
m You may see a moiré pattern while in some resolutions, depending on the
desktop pattern displayed on the screen (the black-and-white checkerboard
pattern frequently causes moiré). To change to another resolution, see
“Changing Screen Resolution” in Chapter 2. To change the desktop pattern,
see the manuals that came with your computer or Macintosh Guide.
No colors appear when you set ambient light.
m Make sure the color depth on your display is set to Millions of Colors. See

automatically. If you want to remove a ColorSync profile, you must do so
manually.
Not all displays attached to the computer appear in the Control Strip pop-up menus.
m Make sure the display is set up correctly and the display power is on. See
“Connecting the Display to Your Macintosh Computer” in Chapter 1.

doesn’t appear on the Control Strip menus; then, close the control panel.
